How it work's
In order to place dental implants into the bone of the jaw, there has to be sufficient bone in order to hold the implant firmly. In some instances, there is not sufficient bone present and so “grafting” can be carried out in order to improve this. Bone can be taken from elsewhere in the jaw (where it is plentiful) and moved into where it is lacking.
Bone substitutes (from other sources) can also be used in some cases, where the amount of bone that needs to be replaced is small.
